Method of producing gold powders and the use thereof

ABSTRACT

The present invention provides a method for producing gold powders. The method comprises providing a vacuum environment and using an electric target to vaporize a source gold to produce gold powders. A spinner is operated and provides ultrasonic vibration effects. The spinner has cooling devices on the inner wall of spinner to cool down the up-rising gold powers and reduce the adhesive force of the gold powders. A static-electronic collector is then used to collect the gold powders.

FIELD OF THE INVENTION

[0001] The present invention relates to a method of producing fine gold powders and the use thereof. The present invention may produce gold powders with high purity and improved uniformity in size and shape that may be used medically.

BACKGROUND OF THE INVENTION

[0002] Gold foils, or thing gold sheets, have been believed have medical use in traditional Chinese medicine references and are utilized in Chinese medical sciences. In addition, the use of gold foils for increasing life expectations and strengthen health. The gold foils have been used in Europe and United States for cosmetic uses, such as for whitening or wrinkle-eliminating products. Gold compounds such as gold contained salts have been used for curing immune system related diseases, such as arthritis. Gold is an inertia metal and is non-toxic.

[0003] Gold is a stable inertia metal with high level of expandability. In the traditional medical uses, the medicines for curing arthritis are gold compounds like gold-contained salts. Known methods of producing gold compound for medical uses include electrolyzing, synthesizing, melting, deposition, or hammering approaches to obtain gold-containing compounds or products. The making of these products for medical increases the value of the existing compounds by adding or increasing the percentage of gold.

[0004] However, all these traditional approaches are not able to produce gold or gold containing compounds of high purity. Other compounds and chemical elements are added. The existing problems reduce the value of the gold products and also affect the medical effects or the absorbability of the final medical products.

[0005] There is general public belief that since gold is a non-toxic, inertia metal, the direct digestion of minor amount of gold foil should be harmless, or even helpful, to human bodies. Therefore, businessmen start to sell products containing gold foils. According to their data, one gram of gold, which is about the side of an average sesame, can be made to a gold foil of 0.47 square meter. The eatable gold foil produced in Japan, which represents the current limitation of the gold-expanding technology, can be made to be as thin as one to three one-ten thousand meter, which is as thin as human skin. Mixing a nominal amount of gold into good could be harmless. However, swallowing over-dosed gold by digesting too many gold foils or gold compounds might create health threats.

[0006] According to the general understanding in the field of chemical art, the characteristics of a chemical element will change when it was made in very fine form. Because of the surface effects of extremely fine powers, the physical and chemical characteristics may change dramatically. Research can therefore be done to discover the method of producing fine gold powders and the use of the fine gold powders.

SUMMARY OF THE INVENTION

[0007] The present invention provides a method for producing gold powders. The method comprises providing a vacuum environment and using an electric target to vaporize a source gold to produce gold powders. A spinner is operated and provides ultrasonic vibration effects. The spinner has cooling devices on the inner wall of spinner to cool down the up-rising gold powers and reduce the adhesive force of the gold powders. A static-electronic collector is then used to collect the gold powders.

BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The foregoing aspects and many of the attendant advantages of this invention will become more readily appreciated and better understood by referencing the following detailed description, when taken in conjunction with the accompanying drawings, wherein:

[0009]FIG. 1 illustrates a schematic drawing illustrating the setup of devices that one of the gold powder producing methods of the present invention may use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0010] The present invention provides a method of producing fine gold powders and the use thereof. The present invention may produce gold powders with high purity and improved uniformity in size and shape that may be used medically.

[0011] Referring to FIG. 1, which illustrates the setup of devices that one of the embodiments of the present invention may use, the method provides a vacuum environment, such as by the use of a vacuum chamber 10. An electric target 12 is used to vaporize a piece of gold as the source material to produce gold powders. The gold piece on the electric target 12 may be electrified to produce gold vapor. On top of the electric target 12, a spinner 14 may be operated in a way that create ultrasonic vibration effects, usually by the design of the spinner 14 or by adding a ultrasonic vibrator 16. As an illustrative example, the ultrasonic vibration provided can be about 20,000 times per second. Skilled artisans may vary the vibration rate dramatically to fine-tune the results of producing gold powders.

[0012] In addition, a cooling device 18 may be provided to cool down the uprising gold powers and reduce the adhesive force of the gold powders. As an example, the cooling device 18 may be cooling pipes that are installed on the inner wall of the spinner 14. As the result of the cooling effects on the gold vapor, the gold powders are adhered loosely on the inner surface of the spinner 14, and then a static-electronic collector 20 may be applied to collect the gold powders, such as by brushing down the gold powders. Extremely fine gold powders can therefore be obtained.

[0013] Experiments conducted have shown that the fine powders produced by the present invention can be used to provide proper and safe dose for medical use. As an example, the gold powders can be about 1 micrometers to 1 nanometer in size. The medical use of the gold powers may have the effects of resisting tumors and/or strengthening immune systems of human bodies, or even animals.

[0014] The gold powers produced by the method can reach high purity, such as 99.9%. The method overcomes the problems of the traditional methods in not being able to provide high purity. In addition, the method of the present invention can be applied for mass production that reduce the production costs and achieve economical levels of production.

[0015] The method of the present invention can also be applied for other metals. When metals are recreated in extremely fine powder form, they can be used for different purposes and achieve different functions or medical effects. In sum, the present invention provides a method of producing fine gold powders with increased efficiency and reduced cost. Upon understanding the principle and spirit of the present invention, a person skilled in the art may apply the invention for producing fine powders for gold or other metals.

[0016] As is understood by a person skilled in the art, the foregoing descriptions of the preferred embodiment of the present invention are an illustration of the present invention rather than a limitation thereon. It is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims. The scope of the claims should be accorded to the broadest interpretation so as to encompass all such modifications and similar structures. While the preferred embodiment of the invention has been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
